UNITED SI THOMAS G. CRETNEY, OF MADISON, WISCONSIN.

TRAFFIC MARKER.

Application filed December 7, 1923. Serial No. 679,246;

To aZZ whom it may concern:

Be it known that I, THOMAS G. CRETNE), a citizen of the United States, residing at: Madison, in the county of Dane and State of Wisconsin, have invented certain new and useful Improvements in Traffic Markers, of which the following is a specification.

My invention relates to traiiic guides adapted to safely regulate trafiic at street or highway intersections and aims generally to improve such devices.

According to my invention, the guide is preferably fixedly secured to the surface of the street or other pavement between the curb lines or slightly back from the curb lines whereby to create a zone of safety for pedestrians between opposed lines of traffic.

The guide according to my invention may be constructed of metal or of other suitable material and is of such construction as to provide an adequate display surface for suitable warning indicia and allow vehicle wheels to pass thereover without serious obstruction or shock.

In the accompanying drawings wherein one embodiment of my invention is selected for illustrative purposes,

Fig. 1, is a diagram of two intersecting streets illustrating the location of my traffic v markers in the street or roadway;

Fig. 2, is a plan of my stop marker;

Fig. 3, is a front elevation, with the pavement partly in section;

Fig. 4, is a side elevation, with pavement partly in section.

Similar numerals refer to similar parts throughout the several views.

In the illustrated embodiment of the invention, the marker comprises a member, which may be formed of a metal casing 1, preferably of general rectangular shape, formed with an inclined rear wall 2 and side walls 3 and a gradually sloping flat top portion 4, inclining from the front edge of the casing 1 toward the tops of the rear wall 2 and side Walls 3 and providing a relatively large flat display surface. Upon the top 4 are suitable traflic or safety warning indicia, preferably cast in large integral embossed letters or characters. Suitable warning indicia or characters may be formed on other side walls if desired, and preferably I provide a suitable warning to traflic approaching from the opposite direction on the rear wall. The warning indicia or characters on the top, sides and rear of the marker, if

suitably embodied in large embossed letters, protect the painted or otherwise finished surface of the casing 1 between the letters or characters from. damage. and wear by vehicle wheels which may pass over the marker. A flange 5 extends entirely around the bottom, and pocket 6 extends inwardly fromthe side flanges. Holes 7 are located through the flanges preferably partly with-' in the pockets for receiving bolts 8, preferably of the expansion type, for securing the marker to the pavement. Suitable anchors or, calks 9 depend from the flange 5 and small pockets 10 are formed in the casing directly over the same for convenience in. parking for transportation.

To permit stacking of the casings in tiers during manufacture and shipment, the calks 9 of one casing will register with the pockets 10, of the next lower one, and the pockets 6 will nest together, so that long threaded rods may be passed through aligning holes 7, andfitted with nuts at each end, thereby to securely hold the stack together and save the cost of crating or boxing.

In use my marker should be placed in the transverse center of a street intersecting an arterial thoroughfare just before the line of travel of pedestrians in crossing the street from sidewalk 11 to sidewalk 12, thereby stopping vehicles and establishing a safety zone 13. p

This marker may be used as shown in Fig. 1, in combination with traffic guides 14 and 15' as shown in my reissued Patent No.

16,131 dated August 24, 1925, or the guides I 14 may be dispensed with, in View of Keep to right, on the marker. In practice the casing 1 may be filled with cementitious material or left hollow as deemed advantas geous to meet varying conditions of use.

Preferably the upper display surface 4 is disposed at a suitable inclination to the horizontal plane of the bottom edges for prominently displaying traffic indicia but to allow vehicle wheels to pass thereover without serious obstruction or shock. In actual practice I find that good results are obtained if the inclination of the display surface with respect to the horizontal is 15 degrees or slightly less, although the inclination may vary therefrom as deemed advantageous to meet varying conditions of use. In the commercial form shown in the drawings, where the inclination is not over 15 degrees, I find that the display surface is so inclined as, to prominently display traffic indicia and at the same time permit vehicle wheels to pass thereover without serious obstruction or shock.

I claim:

1. A warning marker for location between the curb lines of streets, comprising a substantially rigid member, having a polygonal base, and having the major portion of its upper surface inclined toward one margin, and affording a prominent field for suitable warning indicia, said marker being adapted to allow vehicle wheels to pass thereover without serious obstruction or shock.

52. A warning marker for location between the curb lines of streets, comprising a substantially rigid member, having the major portion of its upper surface substantially flat and inclined toward one margin, to provide a suitable field for warning indicia i over which vehiclewheels may travel, the

adapted remaining portions of said upper surface being inclined downwardly toward the other margins more abruptly and also adapted to allow vehicle wheelsto pass thereover with out serious obstruction or shock. I

3. A street marker for location between street curb lines, comprising a metal member adapted to be anchored to the surface of the street, and provided with a plurality of substantially flat surfaces one of said surfaces being inclined from points adjacent one margin downwardly in the direction of the opposite margin, the remaining surfaces sloping more abruptly toward the first mentioned margin and toward the end margins,

and said inclined and sloping surfaces being adapted in height and inclination to allow the passage of vehicle wheels over the marker without serious obstruction or shock.

4. In a traflic marker, a metallic casing to be secured to a roadway or pavement and formed withv inclined surfaces, each sloping toward the bottom marginal edges of said casing, at least one of said surfaces being more acutely inclined with respect to the bottom edge of said casing than theremaining surfaces, thereby to provide a. prominent field for displaying traftic regulating indicia, and to allow vehicle wheels to pass thereover without serious obstruction or shock.

5. A traflic guide comprlsing a rigid memmember of polygonal ber of polygonal shape adapted to be fixedly secured to a street or roadway and presenting a relatively low-lying obstruction, the main portion of the upper surface of said member being inclined from one edge thereof and disposed at a substantial inclination with respect to the surface of the street or pavement thereby to provide a relatively large display surface for rominently displaying traffic indicia an to allow vehicle wheels to pass thereover without serious obstruction or shock.

6. A traffic guide comprising a rigid shape adapted to be fixedly secured to a street or roadway and presenting a relatively low-lying obstruction, the main portion of the upper surface of said member being inclined from one edge thereof and disposed at substantially fifteen degrees with respect tothe surface of the street or pavement thereby to provide a relatively large substantially flat display surface for prominently displaying traflic indicia and to allow vehicle wheels to pass thereover without serious obstructionv or shock.

7. A traffic guide comprising a rigid metal member of polygonal shape adapted to be fixedly secured to a street or roadway and presenting a relatively low-lying structure,

the major portion of the upper surface of said member being inclined toward one margin and adapted in height and inclination to afford a prominent eld for displaying trafiic indicia and also to allow vehicle wheels to pass thereover without serious obstruction or shock.

8. A traffic guide comprising a member having a, surface facing the approaching traflic disposed at a relatively small angle ofv inclination with respect "to' the surface of the streetcor avement and a comparatively steeply inc ined surface facing in the direction of departure of the vehicles passing thereover, the said first mentioned surface being adapted in height and inclination whereby to promlnently display trafiic indicia and to allow vehicle wheels to pass thereover without serious obstruction or shock.

In testimony whereof I aflix my signature.
